We for the first time developed a green and very simple method towards carbon-dot-incorporated poly(diphenylbutadiyne) nanohybrids (PDPB) through a solid reaction without the need of a template, a solvent and a surfactant. The incorporation of carbon dots into the PDPB nanostructures not only significantly improved visible light absorption but also enhanced photocatalytic performances.

Cadmium (Cd) contamination in water poses a critical global challenge. A novel nanocomposite, montmorillonite (Mt)-supported nanoscale zero-valent iron (Mt-nZVI), synthesized by liquid phase reduction, offers a promising method for effectively removing Cd. The material underwent characterization through various techniques, including X-ray diffraction (XRD) and Scanning Electron Microscope(SEM).

Heterojunctions have garnered significant attention in the field of photocatalysis due to their exceptional ability to facilitate the separation of photogenerated charge carriers and their high efficiency in hydrogen reaction. However, their overall photocatalytic performance is often constrained by electron transport rates and suboptimal hydrogen adsorption/desorption kinetics. To address these challenges, this study develops a g-CN/MoS@MoC dual-effect synergistic solid-state Z-type heterojunction, synthesized through the in-situ sulfurization of MoC combined with ultrasonic self-assembly technique.

Encapsulation of non-noble bimetallic nanoparticles within a zeolite framework can improve the stability and accessibility of active sites, but the single microporous structure and poor metal stability decreased the catalytic performance of the catalyst. Here, 3D hierarchical ZSM-5 zeolite encapsulated NiCo nanoparticles (NiCo@3DHZ5) were synthesized by Bottom-up confined steam-assisted crystallization (SAC) one-pot hydrothermal method and applied to the hydrodeoxygenation of vanillin. A series of characterizations showed that highly stable alloyed NiCo nanoparticles were encapsulated in a framework of 3DHZ5, the strong metal-zeolite interactions resulted in highly dispersed NiCo nano-alloys facilitated hydrogen adsorption and spillover of active hydrogen atoms, and the 3D hierarchical structure promoted oxygenated substrate diffusion, the synergy interaction between the alloy particles confined in the 3DHZ5 pores and the acidic sites on the zeolite surface promoted the selective conversion of vanillin.

We report the synthesis of three nickel complexes based on Ni(NHC)[P(OR)](Ar)Cl and their application in C()-N cross-coupling reactions. Reactions involving secondary amines proceeded at room temperature, while anilines and primary alkyl amines coupled under mild heating. The reported complexes are air-stable as solids, operate at low catalytic loading, and do not require an exogenous ligand.

A method for determination of ten kinds of sweeteners in soybean products by multi-plug filtration cleanup (-PFC) combined with ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The sample was extracted with acetonitrile (containing 1% formic acid), degreased by using -hexane liquid-liquid extraction and purified by solid phase extraction using an -PFC column (Oasis PRiME HLB). The analytes were separated by using a Waters ACQUITY UPLC® BEH C (2.
